Need assistance with combobox navigation

Hi,

I want to use Flash MX 2004 combobox component for my navigation.
What I want to achieve is that when making a selection in combobox,
a specific external xml file is loaded into the textarea component and a
specific photo is loaded into the scrollpane component.

How can I acheive this? Some code examples or links to information pages would be great :slight_smile:
